Prepare to delight your taste buds by following these simple steps to create Grilled Swordfish with Lemon Caper Sauce:

1. Preheat the Grill: Start by preheating your grill to medium-high heat.
2. Marinate the Fish: In a bowl, mix together olive oil, lemon juice, lemon zest, minced garlic, salt, and pepper. Place the swordfish steaks in the marinade, letting them soak for about 10 minutes.
3. Prepare the Sauce: While the swordfish marinates, prepare the lemon caper sauce. In a small saucepan, combine the remaining olive oil, capers, and a tablespoon of lemon juice. Heat gently until warmed through, then remove from heat.
4. Grill the Swordfish: Place the marinated swordfish steaks on the grill. Cook for about 4-5 minutes on each side until the fish is opaque and easily flakes with a fork.
5. Plate the Fish: Once cooked, carefully remove the swordfish from the grill and place it on a serving platter.
6. Drizzle with Sauce: Spoon the lemon caper sauce over the grilled fish, ensuring each piece gets a generous amount.
7. Garnish and Serve: Finish by garnishing with chopped fresh parsley. Serve immediately.

With these straightforward steps, your delicious grilled swordfish is ready to enjoy!
